Application filed October 19,1914.- Serial No. 867,269.

To all 'whom it may concern: i

Be it known ,that I, JAMES W. ARTHUR, a citizen of the United States,residing at Warren, in the county of Trumbull. and State of Ohio, haveinvented a new and useful Improvement in Methods of Repairtion,reference being had to the accompanying drawings, forming part of thisspecification, in which Figure l is a view partly in side elevation andpartly in vertical section and illustrating a portion of the method;Fig. 2 is a perspective view of, a metal fcrmer blank employed 'inconnection with the method; Fig. 3 is a vertical section illustratingthe method as applied to the heel of a boot or shoe; and Fig. 4f is aperspective view of the shaped metal former for heel work.

My invention has relation to a novel method of repairing rubber bootsand shoes, and particularly, the soles and heel portions thereof.

The object of my invention is to provide a` novel, simple, inexpensiveand eiiicient method by which a new sole or heel or partially new soleor heel can be formed on an old boot or shoe.

My invention also provides .means of simple and etcient characterwhereby the sole or heel may be inished with a rolled edge substantiallythe same in appearance as thatof a new boot or shoe, and also by whichany desired surface configuration can be given the sole or heel, or thatconguration may be replaced on rubber shoes after they have been wornsmooth.

In accordance with my invention, I provide a suitably shaped sole piece2 or heel piece 3 of the usual rubber or rubber nia-1i7 terial used inthe formation of the soles and heels of rubber boots and shoes. The bootor shoe tobe repaired is placed on the anvilaof a suitable vise 5, inwhich it can be clamped by means of the screw 6, carrying a suitableclamping plate 7 at its lower end. The piece 2 or 3 is placed on thesole or heel of the boot or shoe in the manner shown in Figs. l and 3. Inext place upon the piece 2 or 3 the metal former blank of bendablemetalpreferably sheet lead. The initial form Ofthis blank for the soleof a boot or shoe is shown at 8 in Fig. 2, while the final form-of theblank for heel irork' is shown at 9 in Fig. 4. This blank is sufcientlylarger than the piece to be applied to the sole or heel to leave asurrounding flange portion 10. Thr parts as thus asl sembled are thenfirmly clamped together by means of the screw 6, and vby means of ahammer or other suitable tool, the projecting edge flanges l0 of theformer blank are turned over and downwardly against .the edges of thepiece 2 or 3, and against the lower portion of the boot or shoe upper inthe manner clearly shown in Fig. 3. The forming surface of the metalblank can be serrated or corrugated so as to impart any desiredconfiguration therein to the bottom surfaceof the sole or heel and alsoto the 'rolled edges thereof.

After the former 8 or 9 has been properly tshaped over the work in-themanner just described, the boot or shoe is removed from the vise, andthe parts are then clamped in any suitable holder and are taken to avulcanizing apparatus and vulcanized in any usual or suitable way. Theformer remains in position during the vulcanizing and when removed atthe completion of the vulcanizinr operation, it leaves'a perfectlyformed sole or heel with a turned and rolled edge of neat and Iinishedappearance subsisantially equal to that of a new boot or sice.

It will be readily understood that my invention is susceptible' of manymodifications in the character of the apparatus employed; that the shapeof the former can be changed to suit any particular job of work, andthat the method is adapted to applying patches to other parts of a bootor The method is extremely simple and can be carried out at acomparatively small eX- pense and without very much manual skill. Themetal blanks employed for the formers being made of lead or similarsoft' metal can be very readily and easily shaped to the work, and afterbeing used can be readily iattened out for use again in subsequent work.to be done in a thorough and finished manner not heretofore possible.

It will also-be understood that my invention may be applied to therepair and vulcanization of other rubber articles.

I claim: l. The method of repairing the soles or heels of rubber bootsor shoes, which con- The invention enables repair work Y sists inapplying a\.,vulcanizable repair piece g a flexible forinerblank of leadto the part to be repaired, then placing over such piece a former blankof bendable metal clamipng the parts securely in place, then bending'the edge portions of saidvblank over the edge portions of the repairpiece and shaping the latter, and then removing the clamping means andvuleanizing; sub stantially 'as described.

3. In the art of yulcanizing, the method which consists in-placing avulcanizable piece over the part to which it is to be vulcanized;thenclamping a solid bendable sheet metah former blank over said piecewith its edges projecting beyond the edges 2.

In the art of Vulcanizing, the method which consists inpiece over the part to which it is to be vulcanized, then clamping asolid bendable sheet metal former blank over said piece with the edgesprojecting beyond the edges of the repair piece, said blank having' asurface configuration, then bending the projecting edge portions of theblank over the edge portions of the repair piece, and thereby impartingthe surface coniguration of the blank to the repair piece, and finallyvulcanizing with the former still in place; substantially as described.

In testimony whereof, I have hereunto set my hand.
